BRAKE-SHOE.

SPECIFICATION forming part of Letters Patent No. 415,736, dated November 26, 1889.

Application filed December 24, 1888. Serial No. 294,514. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES W. RoEPPEE, a citizen of the United States, and a resident of Alliance, county of Stark, and State of Ohio, have invented certain ilew and useful Improvements in Brake-Shoes, of. which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

Heretofore brake-shoes have been formed of equal thickness on their inner and outer edgesthat is, of equal transverse thickness and also of equal longitudinal thicknessthe two ends of the shoe being equally heavy. The disadvantage of this style of shoe is that one end of the shoe is apt to wear more rapidly than the opposite end and the rapid 2o wearing end would,if of equal thickness with the slow-wearing end, become worn down and useless more quickly than the opposite end, compelling the discarding of the entire shoe, although the other end might still be good. So, too, the inner end of the shoe wears more rapidly than the outer edge, owing to the increased engagement of parts, which is due to the tread of the Wheel being worn less than the inner edge of the same. This results in wearing down the inner edge of the shoe before the outer is worn out and necessitates replacing the worn shoe while, in fact, a por tion of the same is still good. Again, the common form of brake-shoe has a sharp angular corner on its inner edge that wears against the neck of the wheel-tire. To obviate this disadvantage, Iform my shoe with an inner edge substantially conforming to the curve of the neck of the wheeltire. To further provide against the inner edge of the shoe Wearing against the neck of the tire, I provide the outer edge of the shoe with a flange that engages and has a bearing against the side of the wheel opposite to the tire. This acts as a longitudinal elevation view of the brake-shoe.

stop to prevent the shoe working inward and A is a brake-shoe having the upper end portion a of greater thickness than lower end portion a and having its inner edge portion 1) of greater thickness than its outer edge portion 1), said inner portion also being of curved formation at c to conform substantially with curve 0 of the neck of the tire of the wheel (J. The outer edge portion of said brakeshoe is provided with the flange d, that has a bearing against the side cl of the wheel and prevents the inner edge of the shoe from working in against the neck of the tire.

The foregoing description and accompanyin g drawings set fort-h in detail mechanism in embodiment of my invention. Change may be made therein, provided the principles-of construction respectively recited in the following claims are employed.

I therefore particularly point out and dis- 2. A brake-shoe provided with a curved inner edge substantially conforming in shape to the curve of the neck of the tire and provided on its outer edge with a flange, said flange adapted to engage with the unflanged side of the wheel, and thereby prevent the shoe from wearing into the neck of the tire, substantially as set forth.

3. Abrake-shoe thicker at one edge than at the opposite edge and thickerat one endthan at the opposite end, said shoe provided on its outer edge with a flange and having its inner edge curved to correspond substantially with the curve of the neck of the tire, substantially as set forth.

In testimony that I claim the foregoing to be my invention I have hereunto set my hand this 20th day of December, A. D. 1888.
